    Hi all,
    
    A nice evening. It started with a mag -1.5 flare from Iri 42 at 01:15:30 UTC 
    before making my positional observations. While waiting for my satellites I saw 
      #27551 (Zi Yuan-2B R/B) at 02:27:30 and the satellite itself (#27550) at 
    02:47. Both were quite easy at mag 3 and 4. I also timed the rotation period of 
    both IGS Fairings (#27702 and 27703):
    Fairing 1 at about 10.3 sec and Fairing 2 at 12.5 sec.
    Both can make sharp bright flashes (mag 0 or -1). They will be very interesting 
    to observe this summer until their reentry this fall.
    
    One surprise was the IGS Adapter (#27701). It looked like a Lacrosse at mag 3 
    and flared to a magnificent -2 at 02:47:30 with a nice orange color at about the 
    same rate as an Iridium.
    
    Here are the postional obs :
